Fasciolosis
The adult liver fluke, Fasciola hepatica, lives in the bile ducts of a wide range of animals, including sheep, cattle, rabits and, less often, horses. It can infect humans causing a painful abdominal disease. The intermediate host in the UK is a mud snail, Lymnaea truncatula. Significant economic losses occur in western parts of the British Isles. Deaths, clinical and subclinical disease in cattle is confined to a younger stock. Fasciolosis is a seasonal disease with more serious outbreaks occurring in some years than in others. A similar but slightly larger species, F. gigantica, occurs in wetter tropical regions.
